Billboard processing process
With the rapid development of our country's economy, urban construction is becoming more and more beautiful, especially when walking on the street at night, everything is flashing Neon lights, and even some bustling streets are brightly lit every night. For example, the billboards and door signs of major banks will be lit up all night, as well as signs for 24-hour supermarkets, expre ss hotels, etc. These signs dot the night sky in the city at night, forming a beautiful landscape. . So do you know what this kind of sign is? In fact, this is a blister light box. Let me introduce it to you!
Blister light box production technology
Blister light box three-dimensional luminous character processing technology
From multinational companies McDonald's, KFC and Pizza Hut to domestic supermarket chains, banks, Jiefang Commercial Vehicle Service Center stores Recruitment, all breeds a huge business opportunity for advertising product logos. Acrylic processing is inseparable from molds. Molds can be made of wood, gypsum, steel, etc. The mold material selection can be determined based on the processing batch size. Wooden molds save costs and are only suitable for small-volume processing, because they will lose water and deform after being used for a long time, making the finished product naturally unsightly and causing trouble in post-production (requiring processing). The pre -production process for blister light boxes and three-dimensional luminous characters is the same: film making → heating (about 160 degrees) → automatic vacuuming → cooling (about 40 degrees) → stripping → trimming → slotting → three-dimensional luminous characters. (Trimming → Bonding words and panels → Block splicing → Blister light box).
Mold making
Mold making can use a woodworking jig saw or computer engraving. The punch must have a slope and a small upper part. The membrane can be removed after defecation. The heating temperature is appropriate. The higher the temperature, the better. When the temperature is high, the acrylic plate will crack and lose its flexibility, and the suction depth will be unsatisfactory. The automatic vacuum blister system and intelligent temperature control automatic control system are the core components of the acrylic processing equipment. Other heating boxes, frames, etc. are simple. There are two types of cooling: natural cooling and air cooling. The timing of demoulding must be mastered. If it is too early, the text will be deformed. If it is too late, it will be difficult to demould, and the possibility of reusing the mold will be small. Trimming is to fix the woodworking trimming machine on an ordinary tabletop and use a straight knife to trim. "Adhesion" is very important in acrylic products. Sealing, firmness and no flow marks are the keys to ensuring the perfection of the product.
Since the size of the text determines the thickness of the acrylic sheet, generally 2mm thick is enough for characters with a height of less than 25 cm. The thickness of the characters should also be less than 2cm. For large characters with a height of more than 2 meters, 5mm is sufficient That’s it. Due to the different spacing between text strokes, the upper half of some text cannot be sucked into place. If the text strokes have the same depth, we can only use the KFC text processing technology, first cut out the words, then cut out the word edges, and then glue them together. This process is similar to the metal lettering process. If there are multiple colors in a picture, you have to make corresponding molds according to different colors. For later docking and matching, the thickness and slope of the acrylic plate should be considered in the mold. A perfect product can also be obtained by sucking out multi-color single-color plates and adding color stickers of different colors, and heating them with a welding and plastic gun. When making a blister light box, the panel and text can also be formed by suction and pre ssure at one time, and then color stickers can be pasted on the surface of the text. But be sure to use high-quality, non-discoloring light box stickers such as 3M.
Overview
The frame of the blister light box is the same as that of the traditional light box, except that the thermal expansion coefficient of the acrylic board is relatively small. Large, the shrinkage is about nine times that of metals. When installing or fixing, consideration should be given to leaving room for expansion and contraction.
If you are facing a regional market, there is no need to install a screen printing machine. Because the quality and processing technology of acrylic determine its high price. From plate making to printing, screen printing is not cost-effective for small batches. If the two are added together, the price is beyond the reach of ordinary users. After receiving an order, go to a professional screen printing factory for printing. The quality is good, the price is low, and you save money. Why not do it?
Through the detailed introduction given by the editor, I believe that everyone has a new understanding of blister light boxes. The night view of our city depends entirely on it. The decoration of these blister light boxes makes our living environment so beautiful. Therefore, it is good for everyone to have a proper understanding of the manufacturing process of blister light boxes. Of course, if anyone wants to open a store, they need to understand it in depth. Made to order. In fact, the application range of blister light boxes is very wide, including construction, advertising display, industrial products, lighting, civil, medical and some special purposes. Of course, this still needs everyone to understand further.
